However, in the above-described conventional clamping jig, the I-bar 1 and the C-bar 3 are held by the clamping jig 8 in the furnace together with the clamping jig 8. Since it is to be inserted and heated, the tip of the screw 15 is crushed or the leaf spring 16 is bent during the repeated use of the holding jig 8. Therefore, when the screws 15 are tightened by being screwed, torque is generated in the rotation direction of the screws 15 and the height direction of the base 9 with respect to each of the bars, and the pressing piece 14 causes I Bar 1, C
There is a problem that the pressing balance of the bar 3 is not constant in the vertical position, and the joining balance becomes non-uniform. Further, in recent years, the size of the I-bar 1 and the C-bar 3 in the height direction in FIG. 3 tends to be minimized with the increase in the density of magnetic disks. When it is not possible to respond properly and when joining bars with different dimensions,
Since the sandwiching jig 8 must be replaced according to its size, it is necessary to prepare the sandwiching jig 8 according to various sizes, which has a problem that the equipment cost is high and the usability is extremely poor. ing.

Further, when the threads of the screw 15 are crushed or galled by the heat, and further, the low melting point glass 4 adheres to the base 9 or the pressing piece 14,
Since the jig needs to be replaced, and the leaf spring 16 also needs to be replaced 4-5 times due to fatigue, etc., the life is extremely short, the maintenance cost is increased, and the number of members is extremely large. Since there are many, there is a problem that the manufacturing cost also becomes high.
